REVERSIBLE PLOW.

SPECIFICATION forming part of Letters Patent No. 232,001, datedSeptember '7, 1880.

Application filed November 26, 1879.

To all whom it may concern:

Be it known that I, AARON S. GLOUGH, of Meredith, in the county ofBelknap and State of New Hampshire, haveinvented an Improved ReversiblePlow; and I do hereby declare that the following is a full and exactdescription thereof, reference being had to the accompanying drawings,making part of this specification- .Figure 1 being a side view of theplow; Fig. 2, a rear view of the same; Figs. 3, 4, and 5, views of partsdetached.

Like letters designate corresponding parts in all of the figures.

I In the construction of myimproved reversible plow I employ a doublemold-board, A, having a double wing, a, in the middle part, and at theextreme opposite edges, respectively, two shares and points, Z1 1), oneoverhanging the concave of the mold-board when the other runs at thebottom of the furrow, and thereby assisting to turn the furrow-slice. Asboth side edges are alike, the operation is precisely the same whichevershare is at the bottom, one turning the furrow-slice to the right andthe other to the left. I pivot or swivel this double m ld-board on amiddle longitudinal line at the under or back side thereof. Thispivot-line is formed at the junction of two landsides, B B, extendingfrom the shares and soles at the points of the moldboard, and formingplanes which meet ata very obtuse angle approximating to a straightline, or one hundred and eighty degrees, as indicated in Figs. 2 and 3.The journals 0 d on which the mold-board swivels turn close up under thebeam 0 and centrally beneath the same, whereby the beam is brought downinto a normal or usual position relative to the mold board and share;and in order to enable the pivotline of the mold-board to be thusbrought close beneath the beam, that part of the beam directly above then1old-board is made of triangular form in cross-section, or broughtnearly to an edge at the lower side, as shown in Fig. 3. The landsidesmay be hollowed somewhat where they are brought into contact with thebeam, in order to enable the mold-board to turn under the beam nearly tothe extent of half acircle, though it is not necessary to give a turningmovement quite to the extent of half a circle.

This pivoting of the mold-board close up under the plow-beam enables meto automatically shift the line of draft so as to properly take 5 land,whichever way the mold-board turns, by very simple and direct means.This consists in securing a rod, D, to the forward journal, 0, of themold-board, or to some part of the moldboard itself, and extending thesame forward under the beam, so as to be in or nearly in line with thejournal and turn with the same, and consequently with the mold-board.This rod terminates beyond its bearing under the forward end of thebeam, with a hook, f, turned to one side, so that the draft-chainhitched thereto will properly direct the beam when turning thefurrow-slice either to the right or the left, substantially as indicatedin Fig. 4. Also, there is or may be attached to the forward end of therod D a clevis-bar or other form of clevis, g, as shown, so as to varythe draft in either direction and still shift automatieally.

Suitable stops it It may serve to hold the clevis steadily in itsposition;

The colter E is attached to one side of the beam, as shown, so as not tobe in the way of the clevis-shifting rod D beneath the beam, and it mayhave a lateral movement given to it by connecting it with the said rod.

The forward journal, 0, of the mold-board turnsin abearing, 7c,projecting downward from the beam, and to furnish a bearing for the rearjournal, d, of the mold-board an arm, '5, ex- 8 5 tends downward fromthe rear end of the beam and nearly at right angles thereto. This armalso extends far enough down to carry the locking device for holding themold-board in its two positions. This consists in a dog, 1, 9o pivotedto and preferably in a slot or mortise of the arm 2', this dog, whenleft free, being provided with a spring or otherwise arranged toautomatically enter one or the other of two slots or mortise-s, m m, ina rim or flange, a, 5 extending along the rear ends of the two landsidesB B of the moldboard, the middle or rear wing of the mold-board beingsupported by a bolster-brace, Gr, attached to the ends of this flange orto the landsides, as shown in 1C0 in Fig. 2. Thelocking-dog iswithdrawnfrom the lock-mortises of the flange by drawing on a rod, 19,extending therefrom up by the side of one of the plow-handles to aposition Within reach of one of the hands of the operator, substantiallyas represented in Fig. 1, or other- Wise.

The handles H H of the plow are bolted to the two sides of another arm,1, extended 11p- Ward and backward from the rear end of the beam.

This reversible plow is exceedingly simple in construction andoperation, strong, and, having little operative complication, is notliable to get out of order.

, What I claim as my invention, and desire to secure by Letters Patent,is-
